x402r Refund Protocol

A secure, transparent refund system for x402 payments. Enable dispute resolution and buyer protection with minimal code changes.

The Problem​

When agents or users pay for services via x402, things can go wrong:

  • An API returns empty data after payment
  • A purchased item arrives damaged or wrong
  • A merchant becomes unresponsive

x402r solves this by routing payments through escrow contracts, enabling trustless refunds and dispute resolution.

How It Works​

  1. Merchant deploys an escrow contract (one-time setup)
  2. Payments are routed through a DepositRelay to escrow
  3. Disputes can be raised on-chain
  4. Arbiters resolve disputes, funds are released or refunded
